Joint Cutting

Separation cuts, expansion joints and floor openings

Joint cutting is the process of creating controlled weak points in a concrete surface to manage where cracking occurs. As concrete cures it begins to shrink, and it continues to expand and contract with temperature changes; joints ensure that this movement takes place along planned lines rather than causing random, uncontrolled cracks.

Expansion joints accommodate temperature-driven movement, while contraction joints control the stresses that build up during curing. Cut with diamond-bladed equipment, these joints play a key role in keeping large floor surfaces durable and free of unplanned cracking over the long term.
